Patent FR-2239190-A1 (FR)
Title: Mower, chopper and blower for forage crops, etc. - has spreader chamber and air cushion to transfer the crop
IPC: A01D43/08
Filed: 1974-06-26
Abstract: A chamber (17) collects the material and is inserted between the loader inlet and the chopper (4) outlet. The chopped material accumulates here and is transfered to the loader unit after uniform distribution by airflow. The chamber has an inspection door (17) providing access to the blower fan (13) and chopper. The system for the transfer of the material uses an air cushion in the chamber, drawn in through an inlet (19) in the chopper lower casing by the blower fan, moving the material and keeping it away from the walls of the chamber, thus reducing friction, and therefore, power requirement.

Title: Wind powered machine to produce energy - has rotors driving turbines producing flow through venturi tube
IPC: F03D9/00
Filed: 1974-09-25
Abstract: The machine has a long vertical tube with reinforcing bands at intervals supported above circular steel plates with central openings within which are held inlet air filters. Within the tube are rotor blades mounted in multiples of three, the blades in each group being staggered at angles of 120 deg. to each other. The turbine formed by the rotors pulls air through the ventrui causing a pressure drop in the throat of teh venturi. An air motor within the venturi is driven by the flow of air and provides the output energy. The machine is controlled by horizontal adjustment of the blades about a diameter through their ends. This is done pneumatically by compressed air from a compressor on the machine.

Patent FR-2281246-A1 (FR)
Title: Fail-safe control for automatic gear box - switches off control and reduces gear ratio if max motor speed exceeded
IPC: F16H59/00
Filed: 1975-07-31
Abstract: The electronic control for the automatic gear box has a fail-safe interlock which monitors the motor speed from the impulses in the ignition coil. If the maximum allowable motor speed is exceeded dthen the main part of the control is switched off. This allows the pressure control valves to gradually switch down the gears until the lowest gear ratio is set. The vehicle is then driven to the garage in bottom gear, even if there is a major failure in the control. The maximum speed can be exceeded if the control fails, either through cable break, of transistor failure, so that a lower gear is set.
Patent FR-2294351-A1 (FR)
Title: Fixing of furniture to walls of friable material - uses bolts attached to bracket and forced against hole
IPC: A47B97/00
Filed: 1975-12-05
Abstract: The cupboard (7) which is installed close to the wall (3) is liable to overturn as shown by the arrow (10), when the doors are open. If the wall is of friable material it is difficult to retain a bolt which resists a tensile force. To overcome this difficulty a bolt is fitted into a hole in the wall (3) near the floor (8). The end of the bolt is rigidly attached to a bracket (13) which is secured to the floor (9) of the cupboard. A tensioning screw (15) forces the bolt upwards in the direction (14) against the side of the hole in the wall so that the force is resisted by compression of the wall material.

Title: Strip material scanning system - uses laser and rotating mirror with position encoding grating to give optical scan
IPC: G01N21/89
Filed: 1976-12-21
Abstract: The optical scanning equipment for examining strip material consists of a laser light source and rotating multiplier mirror. The rotating mirror causes the laser beam to be deflected over the complete width of the band of material under investigation. The scanning beam passes through an angled clear glass screen and light reflected from the material passes to photomultiplier detectors. The beam is partially reflected by the transparent screen onto a grating. Light passing through the grating falls onto a detector whose pulse output is used to encode the position of the scanning beam across the width of the material.

Title: Gill box having non metallic interceptor surfaces - e.g. rolls to guide needle bars around closed path
IPC: D01H5/04
Filed: 1977-04-26
Abstract: A Gill box for drafting and sepg. fibres includes upper and lower assemblies of needle bars which are moved by feed screws in a closed path around guides so that the needle bars of the upper and lower assemblies move together along a linear path, along which the fibres pass and so that the needles penetrate opposite sides of the fibres. At the end of the linear parth, the needle bars are moved transversely by hammers and hit a non-metallic interceptor surface which directs them along a return path. At the end of the return path, the needle bars are moved transversely by hammers onto another interceptor surface which guides them into the linear path. The speed of movement of the needle bars can be increased and noise and wear is reduced.
